Space maintenance refers to the activities and practices aimed at preserving and managing the environment in outer space. This includes monitoring and controlling space debris, which are defunct satellites and fragments from collisions. Effective space maintenance helps ensure the safety of operational spacecraft and the sustainability of space activities. Additionally, space maintenance involves regular assessments of satellite health and functionality. Organizations like NASA and ESA implement strategies to extend the lifespan of satellites and reduce the risk of collisions. By maintaining a clean and functional space environment, we can support ongoing scientific research and commercial activities in space.
